Lifting Service to a New Level

Truck-mounted knuckle-boom cranes are becoming the choice of producers who deliver product below the truck bed to its final destination.As both customers' needs and a young precast concrete industry's design capabilities evolve, many precast products are getting larger and heavier. Many customers' backhoes may not have the reach or the lifting capacity to safely handle a larger septic tank. What's needed is dedicated lifting equipment that can access hard-to-reach areas, and the longer the reach, the better. Getting great reach and lifting capacity from a telescopic crane depends on maintaining an upward boom angle, problematic in tight spaces. Many producers are opting for truck-mounted knuckle-booms for placement of products below grade. Their overall design, which depends more upon the hydraulic operating principle for superior rotational torque, provides superior lifting and lowering capacity at up to 20 feet from the centerline of rotation. Their design has also allowed their lifting-capacity-to-weight ratios to increase in recent years, minimizing their impact on payload capacity.Producers say they select the right model by considering several factors:

Fitting knuckle-boom to customers' changing demands

Maximizing payload capacity by upgrading the truck chassis.

Mounting the crane at the rear of the truck and using auxiliary trailers
